利用GPS进行速度测量的方法研究

Study on the Method of Velocity Determination Using GPS

导弹精确制导、航天器对接、测控设备精度鉴定等军事领域,都要求在使用GPS进行高精度定位的同时,也要获得高精度的速度信息.主要研究了3种利用GPS进行测速的方法,总结了各种方法的特点与优劣,并在MATLAB平台上编程,通过对实测数据的分析比较,对3种方法的精度估计得出了结论.

It is essential for obtaining the high accurate result of both position and velocity using GPS for many military fields, such as the precise guidance of missile, the spacecraft rendezvous and docking and the accuracy evaluation of the tracking instrument etc. Three methodology of computing receiver's velocity are presented in this paper, and the advantage and disadvantage of the methods are discussed on the analysis of the application examples. At last, the estimation of the accuracy of three methods is given out.
